10 Claims.

This invention relates to expellant holders for' sticks of expendable substance such as lipstick and other applicative cosmetics.

There are advantages in the use of all-plastic parts to compose an expellant lipstick holder but some-of these are counteracted by the tendency of mold-produced thin-walled tubular plastic parts to shrink or warp during storage or use. The present improvements are a compromise between the use of all-plastic parts and the use of all metal parts aiming to combine with a relatively thick-walled outermost tubular plastic case and a relatively solid innermost plastic lipstick carrier an intermediate thin-walled sleeve or barrel for actuating the carrier to expel and retract the lipstick.

It is a further object to form such actuating barrel by rolling up to tubular shape an initially fiat sheet of preferably resilient material which may be springy non-corrosive steel or hard brass.

In this combination it is desired to retain the advantages of a plastic outer case having thick enough walls to contain a helical groove that may serve as an expelling screw track and also the advantages of a plastic carrier in whose molded shape is incorporated a lateral lug adapted to track in such helical groove.

Other objects of this invention are to incorporate simplified means in the actuator barrel enabling the same to be rotated by "finger manipulation of an outside ferrule and to be axially constrained and frictionally braked for remaining yieldably in various rotative positions to stay the lipstick at desired extents of protrusion from its case.

The foregoing and other objects are referred to at greater length in the following description of a preferred embodiment of the invention, in which description reference is made to the accompanying drawings wherein:

Fig. 9 shows a development of the bottom end portion of the actuator tube of Fig. 4.

Fig. 10 shows on an enlarged scale a modified construction of the assembled bottom end portion of the lipstick holder making use of the actuator barrel shown in Fig. 4.

In the cosmetic applicator of my copending application Serial No. 535,779, filed May 16, 1944, it is proposed to provide a tubular outer case that, for assembling and disassembling, springs into and out of axially interlocked free swiveling rotatably coupled relation to a cup-shaped ferrule whose rim girds the bottom endof the case. Similar features of construction are employed herein but with modification which novelly includes the provision of an annular space. 2|] of axial extent between an annular thrust surface 2| presented downward by the flanged bottom end 22 of the outer tubular case 23 and a complementary annular thrust surface 24 presented upward by the marginal section 25 of ferrule 26. This space 20 separates and is bordered by thrust surfaces 2| and 24. From this marginal section of the ferrule there arises a thin springy rim wall 2'! that is inwardly lipped at 28 to form an annular bead past which the flanged bottom end 22 of case 23 can be forced with a snap action in assembling and disassembling ferrule fill relative to this case.

The relatively thick tubular Wall of case 23 which may be molded from plastic material contains an internal helical groove or screw track 332 in which rides the follower lug 33 that forms partof the molded shape of the cup-like carrier 3 which also may be made of plastic material and in which is firmly lodged the lipstick 35. Groove 32 runs out or opens through the bottom end-22 of case 23 but at its opposite or top terminus is blind-ended at 3 l. Carrier 34 has the usual vent 3-6 in its floor wall to prevent air trap.

According to the present improvements'an ac tuator barrel 40 having a relatively very thin wall is formed by rolling into cylindrical shape the major area of a springy blank sheet of material which may be of thin spring steel or resilient hard brass and whose developed form, a partially shown in Fig. 9, includes a series of circumferentially spaced tabs 4!, 42 and 43 projecting from its bottom edge that is to extend circumferentially and two larger axially spaced tabs '44 projecting from a lateral or axially directed edge. Barrel 4!) is rotatably' sleeved between the tubular wall of case 23 and the periphery of carrier 34. Tabs 44, when the blank is rolled up, meet the opposite lateral or axially directed edge of the blank and define the top and bottom limits of an elongated axially extending slot 45 through which in assem bly the followerlug-SS ofcarrier-34 projects with.

a loose enoughifitltolslide freely upand'd'ownin such slot as rotary movement of actuator barrel The lipstick is retained against endwise pressure 40 correspondingly impels the follower lug 33. In" conventional manner this rotary movement of, 7

lug 33, while it remains guided in-hel'icalggroove 32, produces axial screw-like movement ofca'rrier 34 relative to the outer case 23. Considering now the novel ears on tabs 4|, 42

and 43, some of which serve tofiange-barrel 4! by being outward bent in Fig, 4, it willrbe seen that other diametrically opposite tabs 4| are left pointing straight downward without distortion other'thanslight curvature which maybeirnparted to them by fiexingvthe 'fiat' sheetzblank into cylindrical form. Tabs 4 l thusafiord'driven shoulders.- or a. driven .lug for rotating barreli lli.

Two other diametrically opposite tabs: 52* are.

bent outward into right angle relationship; to

' thelongitudinalj axis of barrel 40, while two more diametrically; opposite resilient tabs 43 are outwardly' inclined and remain; in slanting relation to the. barre-Ii axis; Thus. tabs" 41 respectively enter" and become'interlocked with notches 46 forming rotary driving" shoulders in-the marginal section. of" .ferrule: 26" in. the; assembled, structure shownin Figs. 1; 2 and 8; Tabs-42' extend. into; and revolve about'iin' the annular path. orspace" zllibetweenv thrust surfaces; 2! and 24at.

is near the top ends of slot and groove 32.

When so projected the applicative' tip of the lipstickl35 is outside of case 23 and ready for use.

inwardof thecase by the frictional resistance of tabs 42 againstthrustlsurface 2i occasioned by the resilient axial thrust of tabs 23 against thrust surface 24. Also this resilient thrust of tabs =43 sets up light axial pressure between bead 28 and V flange 22 resulting in frictional resistance at this 15* point tothe turning of case 23 relative to ferrule. 26. While here shown as continuations of the major area of the blank sheet in Fig. 9, any orall of tabs '41, l2'and 43 may be separate re-' silient pieces or separate pieces resiliently mounted on the actuator barrel 49, The exact width, shape and spacing of these tabs is a matter of choice to suit the materials and degree of frictional resistance desired;

In Fig, 10' the 'disposition of the barrel tabs 41; 4-2 and 43 remains as in Figs. l to 7, inclusive, but there is substituted for the rim wall Zlj'of ferrule 26- a couplingshell" 59 which may be formed Of' p1i&nt( meta-ljor other suitable material, possibly a pl astic, havingian initially inturned flange 30, 5'! at its bottom rim against which is fixedly 35 In assembling, the topof the /rim of'cylindrical "wall of coupling shell 58 isturned inward toform an annular retaining lip 52 which engages andextendwadially outwardbeyond the" full depth i of the bottom" open end of helical groove' 32- as:
